According to a report from the National Academy of Medicine, every individual in the United States will experience at least 1 diagnostic error during his or her lifetime. The 2015 report, Improving Diagnosis in Health Care,1 stated there was “a moral, professional, and public health imperative” to improve the diagnostic process. Although the report attributed diagnostic failures to many factors, including poorly designed health care systems, limitations of health information technology, and the increasing complexity of medicine, it poignantly identified timely, accurate, patient-centered diagnosis as the quintessential competency of the clinician.
